Q. sfc0.x fails with an error like this: PGFIO-F-209/unformatted read/unit=19/'OLD' specified for file which does not exist. In source file naopen.f, at line number 40
A. One possible cause is that 'uncompress' command does not work on your machine to unzip .Z files in libs/con directory. A user suggested a smart solution: making a symbolic link to gunzip or another command that works on your system.
Q. sfc0.x (or other codes) fails to read an input GRIB file.
A. Check your libs/lib/w3lib_xxx/nainit.f because fstat returns a different array on some machines and compilers. First print "status" array and find where the correct file size is, and change the line "isize=status(?)".
Q. Installation/model/script fails with "command not found" error.
A. Check if your PATH in your .cshrc (or equivalent) includes current directory ".". Some of G-RSM scripts assume that the shell searches current directory for executables.
Q. Model (rfcst.x / fcst.x) crashes.
A. Check the last rfcstout.ftxx or fcstout.ftxx . They print out maximum wind speed within the domain at each time step at each sigma level. If you see very large numbers (and turning to *) before the crash, the model blew up. Try decreasing DELTAT in the script (rsim, etc). Different values are assigned for each season (DELTAT_REG_SPRING for MAM, etc). After changing the value, simply run the script again. The model will restart where it crashed before. min(NESTING_HOUR, INCHOUR) * 60 sec / DELTAT should be an integer. It is safe if you always choose a DELTAT where 3600 sec (1 hour) / DELTAT = integer.
